Takasago Fluidic Systems (TFS) is proud to announce the launch of the Portable Medium Exchange System. This system automates the conventional pipetting processes of feeding in and pumping out cell culture medium, which helps reduce your workload during weekends and holidays, and also minimizes the variability between operators.

One major advantage of this apparatus is its economic price of just 1/40 of a conventional fully-automated cell culture system, which usually costs around 5 million yen. This price is achieved by focusing on only the medium exchanging function. The system is designed to be used in incubators readily available in most laboratories. Just place our Medium Exchange System in your incubator to save on costs and space!

The RVA
series is a miniature rocker-style isolation valve suitable for a wide range of
manifolds for in vitro diagnostic, analytical and laboratory instruments. The
rocker moves like a seesaw inside the valve and alternately seals the left and
right valve seats (see below). Its universal or bi-directional flow functions
simplify your manifold designing processes.

An
innovative ultra-small solenoid valve – can be mounted in the smallest of
spaces, miniaturising application space and shortening the length of flow
paths.

2. Highly chemically inert diaphragm valve

PEEK and
Perfluoroelastomer are used for wetted materials. Materials can be changed
according to your requirements.

3. Internal volume
only 4.3 μl

Through pursuing
miniaturisation to the uttermost, internal volume is now only 4.3 μl. The internal
volume of the valve chamber, which can be a dead volume, comprises only 0.75 μl
of this. This contributes to reductions in reagent/sample quantities and improvements
in analysis accuracy.

4. Latching
solenoid valve

The open/closed status of valve is maintained by
permanent magnetic force. No energisation is required to maintain the valve
status. Contributes to energy saving and lower heat generation due to energisation.
Power is required while changing the status (Open to Closed, Closed to Open).
Also, it is necessary to reverse the current’s polarity to change the status.

・Each basic block holds a pair of 2-way XTA valves. Up to 6 blocks can be flexibly joined together to give a maximum of 12 stations. This manifold provides both a cost reduction and a flexible configuration that cannot be achieved by conventional molded manifolds.

・A 2-row construction enables a shorter length of manifold and common channel, which contributes to a small internal volume and easy arrangement on an instrument.

・The extremely inert material ETFE (fluorocarbon polymer) is used for the block.

・A choice of diaphragm material is available: PTFE for the highest chemical compatibility or FPM/EPDM for cost saving.

・In addition to M6 and 1/4-28UNF threads, the special option of the Push-in Fitting is also available for the port connection, which allows quick connection by just inserting the tubing.

The Quaternary Valve is a kind of manifold valve where due to its structure the four channels from the valves all join at one point and connect to the common port(the central port of the product in the above picture). The lengths of the four channels are the same and the flow rate of each is almost identical. This structure is designed to maintain a high accuracy of the mixing ratio of multiple liquids. The product is often used to mix several kinds of eluant gradually in a low pressure gradient unit in a liquid chromatograph. In addition, it can be used to mix chemical liquids accurately or to dispense equal amounts of one kind of liquid.

Features of the Chemically Inert Molded Body 2way/3way Solenoid Valve PKV Series

Molded 2way/3way PKV series solenoid valve now available.

φ4-6 mm diameter aperture, which enables it to be used in a wide-range of fluid control applications for various kinds of analysis; such as IVD diagnostics, medical, and other life science instruments. An elastomer is employed for the seal material, reducing damage to the valve seat from foreign matter in the fluid and associated leak trouble.

This is a demo module exhibiting the mixing and dispensing of two liquids in a chip with Y-shaped internal channels. It is a very compact module (with dimensions of W72 x L125 x H48.2 mm) that is composed of ultra-small syringe pumps and ultra-small inert valves, and is suitable for applications such as μTAS, Lab-on-a-Chip and point-of-care testing (POCT). The chip is made of bonded plastic layers so as to be economical in mass production and disposable. The controller for the operation of this module has a touchscreen that allows users to easily set the dispense volume or the method of dispensing (simultaneously or alternately).

This is just an example of the modules we provide. Besides this, we design and manufacture modules according to your requests to control liquids in various chips. Please feel free to ask us at contact if you are considering making an experimental device for μTAS etc.

The
solenoid-driven slider valve is a kind of shear valve in which a shutter called
a “slider” moves vertically and shuts off the flow path. The pumping volume which occurs
when a diaphragm valve opens and closes, or the dead volume in which some fluid
may stay in the valve is reduced to almost zero,
preventing reduction of accuracy in analysis or fluid dispensation.
Furthermore, the pressure capability of this slider valve is greatly improved.

The size of this diaphragm valve is just 4.2 mm square. This is an innovative and groundbreaking ultra-small solenoid-driven diaphragm isolation valve. The internal volume is now only 1.1 μl which contributes to reductions in reagents and improvements in accuracy.

This valve is a latching solenoid valve in which the open and closed state of the valve is maintained by magnetic force. Contributes to low power consumption, because electricity is consumed only when energized. With the size of 4.2 mm square, it is an innovative and groundbreaking ultra-small solenoid valve with an internal volume of just 1.1μl. This diaphragm valve is suitable for micro fluidic control.
